Show HN: Fun, Open-source Japanese learning Platform inspired by Monkeytype

https://github.com/lingdojo/kana-dojo
3•aladybug•3h ago
As a long time Japanese learner, I've always wanted there to be a simple, free online trainer for learning and grinding Japanese kanji and vocabulary - like Monkeytype in the typing community (fun fact: we actually have 2 Monkeytype devs on our team now!).

I'm doing this because I grew tired of all the subscriptions and paywalls, which are unfortunately very common in the Japanese learning apps market. That's why I want to make the most fun, user-friendly and customizable platform for learning Japanese currently available, and the first one that is (and will be, forever) completely free, ad-free and open-source - driven not by profit, but made by the community, for the community. We already managed to get around 600 stars on GitHub and about 7k monthly users for the app. That being said, I recognize that the app is still in its very early alpha stages and is, objectively speaking, behind paid Japanese learning solutions (at least for now) - which is why I want to change that and make it the first entirely free and open-source platform for learning Japanese to provide a real, high-quality alternative to all the current paid Japanese learning resources, which I believe we can achieve with the open-source community's help. Why am I doing this? Because weebs deserve to have a free, open-source learning platform too (I'm one of them, don't judge...)
